According to reports out earlier, Best Buy (NYSE: BBY) is looking to have its stores be more Apple-like: there's a "Genius Bar" area for Q&A, easier color scheme, ability to purchase things from locations within the store, and more. That's all well and good (and speaks volumes about how Apple (Nasdaq: AAPL) store layout is pure magic).

So, why is RadioShack finishing the session about 4 percent?

Wouldn't a more shopper-friendly setup from Best Buy attract shoppers from RadioShack?

Maybe it's the opposite: customers will feel like they will be pressured to buy something while in Best Buy, avoiding the stop altogether.

At the end of the trading day, Best Buy ended up a smidgen lower, off about 0.05 percent.
